次の英文を読んで、ここで述べられているinflammation(文全体で)について、４００字程度でまとめなさい。［＊印のついた語句は注を参照にしなさい。］

   What does an injured toe or a splinter* in a finger have to do with your risk of developing Alzheimer's disease, suffering a heart attack or dying from colon cancer*? More than you might think. As scientists look deeper into the fundamental causes of those and other illnesses, they are starting to see links to an age-old immunological defense mechanism called inflammation --- the same biological process that turns the tissue around a splinter red and causes swelling in an injured toe. If they are right --- and the evidence is starting to look pretty good --- it could radically change doctors' concept of what makes us sick. It could also prove a great source of profit to drug companies looking for new ways to keep us well.

・    Controlling immune response may cut bird flu death rate p1105　Helen Pearson

・    Fatal outcome of human influenza A (H5N1) is associated with high viral load and hypercytokinemia pp1203 – 1207

[Abstract]

Avian influenza A (H5N1) viruses cause severe disease in humans^{1, 2}, but the basis for their virulence remains unclear. In vitro and animal studies indicate that high and disseminated viral replication is important for disease pathogenesis^{3, 4, 5}. Laboratory experiments suggest that virus-induced cytokine dysregulation may contribute to disease severity^{6, 7, 8, 9}. To assess the relevance of these findings for human disease, we performed virological and immunological studies in 18 individuals with H5N1 and 8 individuals infected with human influenza virus subtypes. Influenza H5N1 infection in humans is characterized by high pharyngeal virus loads and frequent detection of viral RNA in rectum and blood. Viral RNA in blood was present only in fatal H5N1 cases and was associated with higher pharyngeal viral loads. We observed low peripheral blood T-lymphocyte counts and high chemokine and cytokine levels in H5N1-infected individuals, particularly in those who died, and these correlated with pharyngeal viral loads. Genetic characterization of H5N1 viruses revealed mutations in the viral polymerase complex associated with mammalian adaptation and virulence. Our observations indicate that high viral load, and the resulting intense inflammatory responses, are central to influenza H5N1 pathogenesis. The focus of clinical management should be on preventing this intense cytokine response, by early diagnosis and effective antiviral treatment.

次の英文を読んで、下線部its flawsについて、具体的かつ簡潔に200字程度でまとめなさい。
Sweden has the most comprehensive health care system in the world. All Swedish citizens are covered by national health insurance financed by contributions from the state and employers.
   Medical treatment is just one component of Sweden's broad system of health maintenance. For example, people who are sick or must stay home with sick children receive 90 percent of their salaries. Swedes are given parental leave at the birth of a child, and all Swedes are guaranteed a pension.
   This comprehensive system is not without its flaws. The first problem is its costs. Socially responsible wellness is expensive, running about35 percent of each employee's salary, in fact a rate far in excess of the rest of the world. As a result, the system faces a serious payment crisis in the immediate future and in the long term.
   Sweden's medical system is also very inefficient. Swedes have not solved the twin problems of getting rid of waiting lines and getting physicians and other health care workers to work. With salaries of these medical personnel guaranteed, regardless of how many patients they see, the system is marked by a lack of productivity. When reporters visited Sweden's largest hospitals on a weekday morning, a peak period when 80 of 120 surgeons were on duty, they found 19 of 24 operating rooms vacant. Their photos of dark and empty operating rooms-at a time when there was a one- to two-year waiting period for hip replacements and eye operations --- provoked a public outcry. Due to public pressure and greater accountability, efficiency is up.[慶応・看護より]
